Appendix A Pin Assignments
UTP Port Pin Assignments
The UTP ports use RJ-45 Unshielded Twisted Pair (UTP) cabling. Connector pin numbers and pin wiring assignments are listed below in Figure A-1 and Table A-1, respectively. Twisted-Pair cables can be wired with either straight- through or crossover pin assignments. Both wiring schemes are mentioned in "Appendix B Cabling Guidelines" for reference in creating a twisted-pair cable.

UTP Port
Each UTP port is configured as “MDI-X”, or internally crossed. By default, all repeating and switched UTP ports are generally configured as MDI-X, unless otherwise specified. The last UTP port (port 5 on the KNS500/WG and port 8 on the KNS800/WG) is linked to a cascade switch that allows it to support UTP cabling in the straight-through (MDI) and crossover (MDI-X) wiring configuration. See page 7 “Notes on MDI and MDI-X” for details.
